🌈 Make sense of the number order
Missing number worksheets help SR KG children notice gaps in a counting sequence and use nearby numbers to find what belongs there. Start with a short familiar range, read the row aloud and point to each place. This page combines a missing numbers online quiz with ten interactive activities. The online practice includes easier rows and supported extension tasks up to 100.
🔢 Begin with missing numbers 1 to 20
A missing number worksheet 1 to 10 can begin with one gap between two visible neighbours. Extend to 1 to 20 as children recognise the numerals and count on from different starting points. Encourage them to check both sides of the gap rather than restart at one every time. Revisit counting 1 to 10 worksheets and SR KG counting 11 to 20 worksheets when helpful.
🚂 Continue across a ten boundary
Sequences such as 38, 39, blank, 41 let children explore how counting continues through forty. Use a labelled track, movable cards or a spoken count to support the change. Missing numbers 1 to 50 and 1 to 100 activities are extensions for children ready for those ranges. Choose the amount of support according to the child’s current number knowledge, rather than expecting every range at once.
🧩 Read the rule before filling a grid
A counting row may go forward by one or backward by one. A ten-column number chart increases by one across a row and by ten down a column. Read the stated layout instead of assuming every grid follows the same arrangement. In the chart activity here, only part of a ten-column chart is shown. Connect these ideas with before after and between numbers worksheets and SR KG skip counting activities.
✏️ Use printable and online practice together
Use the existing download option for the printable missing number worksheet. The online activities provide additional examples and do not claim to reproduce the PDF’s exact number ranges. Children can repair gaps, arrange number tickets, compare clue cards and create a small missing-number puzzle. The tracing board offers red and black pens for adult-reviewed writing. Continue with counting 21 to 50 and counting 51 to 100 worksheets when ready.
💬 Missing Number Worksheet FAQs
What are missing number worksheets?
They show counting rows, tracks or grids with gaps. Children use the stated number rule and nearby labels to work out the missing values.
How do I teach missing numbers to an SR KG child?
Start with a short counting row and hide one number. Say the row aloud together, find the missing numeral and check the next number too.
Which number range should children start with?
Use a range the child recognises comfortably, such as 1 to 10. Extend gradually to 20, 50 or 100 when appropriate.
How can children find a number between two neighbours?
Count forward from the left neighbour and check that the answer is one less than the right neighbour when the row increases by one.
How do I help with missing numbers across 29 and 30?
Show a short strip such as 28, 29, 30, 31 and 32. Count across the boundary and connect each spoken word with its numeral.
Do all missing-number rows count forward?
No. Some count backward or use another stated step. Read the instruction and compare several visible neighbours before filling gaps.
How does a ten-column number chart work?
On a standard chart increasing left to right, moving one place right adds one and moving one row down adds ten. Check the layout because other grids can use different rules.
Should children always count from one to find a gap?
Encourage counting on from a nearby known number. A number track or chart can support this until the sequence becomes familiar.
What if a child can say numbers but cannot recognise their written forms?
Use matching cards, counted groups and a short labelled number line. Practise linking the spoken number with its numeral in a mixed order.
Where can I download the missing number worksheet?
Use the existing download option on this worksheet page. The quiz and games provide separate online practice.
